Objective To understand the clinical features of acute renal failure(ARF)as the initial presentation of systemic lupus erythematosus(SLE).Methods Eight cases of ARF in SLE from Jan 1995 to Apt 2006 were investigated,descriptive analysis and literature review were performed.Results①The symp- tom of ARF in SLE was mainly oliguria,with severe accompany symptoms and complications.②The level of leucocyte and hemoglobin was low in laboratory tests,also the complement level decreased significantly.The most frequent renal pathology was typeⅣ,Ⅳ+ⅤLN.③Large dose steroid and CTX were the mainstay of treatment.In addition,SCUF,CVVHDF and hemodialysis could be used for lethal conditions.Conclusion ARF can be the first manifestation of SLE and it usually represents more severe disease and more complica- tions.Large dose steroid and CTX can improve prognois.In cases refractory to steroid and if the effect is obso- lete,CTX treatment SCUF,CVVHDF and hemodialysis can be use.

Objective To propose a new blood purification modality-hemodialysis with plasma- based dialysate (HD-PBD) plus high volume hemofiltration (HVHF) for patients with liver failure, and to evaluate the effect of this treatment on plasma cytokines.Methods Twelve patients with liver failure were included in this study.All patients received HD-PBD therapy in the first 6 hours,and then were treated with HVHF for 24 hours with the same filter (AV600).The levels of TNF-?,IL-1?, IL-6 and IL-8 in plasma before and after HD-PBD plus HVHF for 6 and 24 hours were examined respectively by ELISA,and changes of clinical parameters were observed at the same time point. Serum bilirubin,total bile acids (TBA),serum ammonia,blood urea nitrogen (BUN) and serum creatinine (Scr) were detected before and after treatment.Arterial blood gas analysis and the concentration of electrolytes were monitored before and after treatment.Results (1)HD-PBD for 6 hours was more effective than HVHF for 24 hours in removal of serum bilirubin and TBA(P＜0.05). (2)Serum ammonia,BUN,Ser,arterial blood HCO_3~-,PCO_2,PO_2 and electrolytes did not show significant difference before and after HD-PBD (P＞0.05),but these parameters significantly changed before and after HVHF (P＜0.05).(3)The average level of serum bilirubin was sharply decreased after HVHF for 24 h following HD-PBD(P＜0.05).(4)After HD-PBD plus HVHF,there was a marked reduction of the plasma levels of TNF-?,IL-6 and IL-8.Conclusions HD-PBD plus HVHF,a newly proposed modality for patients with liver failure,can effectively decrease serum bilirubin,TBA,BUN,Scr,ammonia and cytokines,and adjust water-electrolyte as well as acid- alkali balance.It is a low-cost,safe,simple and convenient therapy.

AIM: To determine the relevance of NADPH oxidase subunit p22hox and the expression of superoxide anion on ventricular remodeling in myocardial infarction (MI) rats. METHODS: MI of Sprague-Dawley rats were established by left anterior descenting coronary artery ligation. 8 weeks after MI, Doppler echocardiography, hemodynamic study and histomorphometry were performed to analyze the ventricular remodeling. The level of thiobarbituric acid reactive substance in plasma and myocardium were measured, and the distribution of superoxide anion was observed with laser scanning confocal microscope. The expression of p22phox mRNA and protein level was detected by RT-PCR and immunohistochemistry. RESULTS: The left ventricular remodeling was significant in MI rats, also the level of thiobarbituric acid reactive substance increased in the plasma and non-infarcted myocardium. The expressions of p22-phox mRNA and protein levels, and superoxide anion increased in infarcted and non-infarcted myocardium in MI rats. CONCLUSION: Our results suggest that the expression of NADPH oxidase and its derived superoxide anion may take part in left ventricular remodeling through oxidative stresss after MI.

BACKGROUND: Fibrin glue has been demonstrated to function as a kind of biomaterial with high quality. It has been used in nerve tissue engineering and proved to be a kind of scaffold for some cells.OBJECTIVE: To explore the biocompatibility of fibrin glue and olfactory ensheathing cells (OECs).DESIGN, TIME AND SETTING: An in vitro control trial based on cytology was performed at the Institute of Neurobiology,Nantong University from August 2007 to February 2008.MATERIALS: Fibrin glue was made of fibrin and catalyst, and OECs derived from rats' olfactory bulb were normally primary-cultured.METHODS: OECs were divided into control (OECs clone spheres were cultured alone) and in fibrin glue (OECs clone spheres were cultured and combined with fibrin glue) groups. After 1 week of culture, the proliferation of OECs were observed by convert microscope and detected by S-100 immunofluorescence histochemical staining.MAIN OUTCOME M EASURES: OECs morphology, cell count, the area of the cell bodies and the perimeter of the cell were determined.RESULTS: OECs could survive, migrate in fibrin glue, and float in the fibrin glue in the lower layer. After 7 days of incubation, cell body exhibited fusiform or triangle, predominantly bipolar or bipolar. The number of the S-100 positive cells was more, and cell bodies were larger in fibrin glue group than control group (P < 0.05). However, there was no obvious difference between two groups in cell perimeter (P > 0.05).CONCLUSION: Fibrin glue has good biocompatibility with OECs, and OECs can survive and migrate in fibrin glue.

Objective To evaluate the performance of China Infectious Disease Automatedalert and Response System(CIDARS). Methods A retrospective analysis was conducted on data related to the warning signals, the outcome of signal verification, the field investigation of CIDARS,and the emergent events reported through Public Health Emergency Events Surveillance System from July 1,2008 to June 30, 2010 in Zhejiang province. The performance of CIDARS was qualitatively evaluated by indicators on its sensitivity and rote of false alarm. Results In total, 26 446 signals were generated by the system which involving 17 diseases, with an average of 2.83 signals per country per week. Among all the signals, 99.95% of them were responded. 0.90% of the signals were judged as suspected events via the preliminary verification, and 30 outbreaks were finally confirmed by field investigation. The sensitivity of the system was 69.77% with the false alarm rate as 1.39%. Conclusion The system seemed to have worked on the outbreak early warning of infectious diseases and could directly reflect the anomaly event emerged from the infectious disease reporting system.However, more efforts should be paid to the following areas as how to decrease the false positive signals, select suitable thresholds and increase the quality of data in order to enhance the accuracy of the system.

Pancreatic tuberculosis (TB) is extremely rare and mimics pancreatic carcinoma both clinically and radiologically. This paper discusses the occurrence of 2 heterogeneous masses located in the head and tail of the pancreas in an adult male. In this patient, laparotomy was performed because of the high suspicion of pancreatic carcinoma. Intraoperative fine needle aspiration biopsy revealed the coexistence of pancreatic carcinoma with pancreatic TB, and a combined resection of the distal pancreas and spleen was successfully performed. Following surgery, the patient received standard chemotherapy for TB. At 7-month follow-up, computed tomography showed resolution of the mass in the pancreatic head. Clinicians must maintain a high index of suspicion for pancreatic TB in patients with pancreatic masses. The coexistence of malignancy and TB should be considered when patients present with multiple pancreatic masses.
